Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed March 12, 1914. Serial No. 824,235.

To all whom it may concern:

Be it known that I, FRED N. LIVINGSTON, a citizen of the United States,residing at Seattle, in the county of King and State of Washington, haveinvented certain new and useful Improvements in Pumps; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to pumps and has for an object to employcentrifugal force for operating cylinder and piston pumps.

A further object of the invention is to provide a non-rotatable diskwhich is given a gyratory movement by a rotating overbalanced wheel ormember.

With these and other objects in view the invention comprises certainnovel constructions, combinations and arrangement of parts as will behereinafter more fully described and claimed.

In the drawings: Figure l is a view of the pumping apparatus in topplan, parts being broken away to show the internal construction. Fig. 2is a view of the device in section as indicated by line 22 of Fig. 1.

Like characters of reference designate corresponding parts throughoutthe several views.

The improved pumping apparatus which forms the subject matter of thisapplication comprises a table 10 supported in any approved manner asupon the legs 11, it being understood that the supporting apparatusforms no part of the present invention.

Centrally through the table 10 an opening 12 is produced preferablyhaving inclined edges as indicated at 13. Also centrally beneath thetable a shaft 14: is journaled with a shaft 15 connected therewith by auniversal joint shown conventionally at 16. The shaft 15 is alsoprovided with a roller 17 which rolls upon the inclined edge of theopening 12.

Upon the upper end of the shaft 15 which extends above the table 10 awheel 18 is mounted having at one side a weight 19 which causes theshaft 15 to tilt to one side into engagement with the edge of theopening 12.

It will be obvious that when the shaft 14 is rotated in any approvedmanner as by power applied to the pulley 20 the weight 19 will bycentrifugal action tend to move the wheel 18 and the shaft 15 in thedirection of the weight itself.

Mounted upon the table 10 are a plurality of cylinders 21 shown in thedrawing as four in number but it is to be understood that the number ofsuch cylinders is wholly immaterial to the present invention. Thecylinders are pivoted upon the table as indicated at 22 so that they arefree to oscillate in a horizontal plane. Within the cylinders 21 pistons23 are mounted to reciprocate controlled by piston rods 24. The pistonrods 2& are connected with a disk 25 freely embracing the shaft 15 andmovable thereby in a gyratory circuit under the impulse of the weight19. All but one of the piston rods 24 are pivoted to the disk asindicated at 26 but one is rigidly secured as indicated at 27 so thatthe disk is held against rotation thereby.

It is obvious, therefore, that as the shaft 14 is rotated through themedium of the centrifugal apparatus as described the disk 25 will begiven a gyratory movement which will cause the reciprocation of thepistons 23 within the cylinders 21, the cylinders themselves respondingby oscillating to such gyratory movement.

The reciprocation of the pistons within the cylinders may be employedfor any usual ordinary or desired purpose. As shown in the drawing areceptacle 28 is in communication with such cylinders by means of pipe29 which communicates with the several cylinders by means of flexiblecouplings 30. The flexible couplings are provided to permit oscillationof the cylinders. As shown at Fig. 1 the device would probably beemployed as an air compressor and check valves 31 for inlet and 32 foroutlet are provided. It will be obvious that when the pistonsreciprocate within their cylinders as above described air will be drawninwardly successively through the several check valves 31 upon theoutstroke of the piston and will be compressed within the cylinders andforced through the check valves-32, flexible couplings 30 and pipe 29into the receptacle 28 upon the instroke of the piston.

The greatest object of constructing the device is for economy of powerwhich is especially noticeable in the matter of starting. When power isfirst applied to the pulley 20 it is obvious that the wheel 18 willrotate without any gyratory movement until to overcome the resistance ofthe cylinders and pistons whereupon the gyratory movement of the partsbegins and continues as long as the drive keeps the speed up to the 7required momentum;

I claim:

1. In a pumping apparatus, a table; a plurality of cylinder and pistonpumps mounted upon the table; a shaft extending through the table; aweight carried at one side of the shaft tending to tilt the shaftagainst the table; a disk carried by the shaft and pump pistonsconnected with the disk adapted to permit gyratory movement of the disk.

2. In a pumping apparatus, a table having an opening therethrough; aplurality of cylinders and piston pumps surrounding the opening; a shaftextending upwardly through the opening in the table; a weight carried bythe shaft tending to tilt the shaft into engagement with the opening; adisk embracing the shaft and adapted to receive gyratory movementtherefrom; and connecabove the table and embracing the tiltable' shaft;and pump members connected with the disk.

In testimony whereof I aflix my signature in presence of two witnesses.

FRED N, LIVINGSTON.
